4. Setup

4.1. Charging the Device

The device is powered by an internal 3.7V rechargeable lithium-ion battery. Before first use, or if the battery indicator is low, charge the device using the provided USB cable.

Connect the USB charging cable to the device's charging port.
Connect the other end of the USB cable to a standard USB power adapter (not included) or a computer USB port.
The charging indication lamp will illuminate during charging. It will change color or turn off when charging is complete.

4.2. Powering On/Off

Press and hold the On/Off button for a few seconds to power the device on or off.

4.3. Initial Warm-up and Calibration

Upon powering on, the device will undergo a warm-up period of approximately 20 seconds. During this time, ensure the device is in a clean, gas-free environment to allow for proper calibration to a zero baseline. The display will show a countdown or indicator during this process.

5. Operating Instructions

5.1. Gas Detection Process

After the warm-up period, the device is ready for use.
Direct the flexible sensor head towards the area where a gas leak is suspected. Move the sensor slowly along pipes, connections, and appliance surfaces.
Observe the LCD display for gas concentration readings. The device will show values in units such as %LEL (Lower Explosive Limit) or ppm (parts per million), depending on the selected unit.
The device will emit an audible alarm and provide a visual indication on the LCD when the gas concentration reaches a preset alarm threshold. The alarm intensity may increase with higher gas concentrations.

5.2. Interpreting Alarms

The device features both audible beeps and visual indicators (on the LCD) to alert you to gas presence.

A rising gas concentration reading and an active alarm indicate the presence of combustible gas. The higher the reading and the more frequent/intense the alarm, the greater the concentration of gas detected.

5.3. Unit Selection

Use the 'UNIT' button to cycle through available measurement units for gas concentration, typically %LEL and ppm.

5.4. Applicable Scenarios

The Aicevoos FC-Rechargeble Natural Gas Detector is suitable for detecting leaks in various locations:

Gas pipelines and connections.
Gas appliances (stoves, ovens, water heaters).
RV propane tanks and associated lines.
Areas where coal gas or other combustible gases might be present.

6. Maintenance

Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the sensor head is kept clean and free of debris.
Battery Care: Recharge the battery when the low battery indicator appears. Avoid fully discharging the battery frequently to prolong its lifespan. If storing the device for an extended period, charge it periodically.
Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
Sensor Protection: The flexible sensor neck is durable, but avoid excessive bending or sharp angles that could damage internal wiring.

7. Troubleshooting

Problem	Possible Cause	Solution
Device does not power on.	Battery is depleted.	Charge the device fully using the USB cable.
No gas detection or inconsistent readings.	Sensor head is dirty or obstructed. Device not properly warmed up/calibrated. Gas concentration is below detection threshold.	Clean the sensor head gently. Ensure the device completes its 20-second warm-up in a clean air environment. Confirm the presence of gas with another method if possible (e.g., soapy water for visible bubbles on connections).
Alarm sounds continuously in clean air.	Sensor may be contaminated or requires recalibration.	Power off the device, move to a known clean air environment, and power on again to allow for proper warm-up and baseline calibration. If the issue persists, contact customer support.
Display is dim or unreadable.	Low battery.	Recharge the device.
